MOOSE, Wyo. — Sunday marks the end of over-snow access in Grand Teton National Park (GTNP) for the 2022/23 winter season as plowing operations begin in preparation for spring.

Winter grooming of the 14-mile section of Teton Park Road between Taggart Lake Trailhead and Signal Mountain parking area ended on Friday, March 10. The road will remain open for winter activities until Sunday, March 20, when snow removal operations begin.

For safety reasons, visitors may not access Teton Park Road once snow removal operations are underway. Rotary equipment and plows may be working at any time, and the roadway will be closed to all users until the snow removal operations are completed. Skiers and those on snowshoes using areas adjacent to the roadway are cautioned to avoid the arc of snow blown from the equipment because pieces of ice and gravel may be thrown great distances. 

The Teton Park Road is anticipated to be accessible to activities such as cycling, roller skating, skateboarding, roller skiing, walking, jogging and leashed pet walking in early April, depending on weather conditions.

The Teton Park Road is expected to be open to motor vehicles on May 1, depending on weather conditions. 

Other park roads that are normally closed during winter will remain closed to vehicular traffic when posted or gated. The opening dates of these roads vary from year to year and are dependent on weather, snow, plowing progress, wildlife activity and road conditions.  

The Teton Park Road will open to motor vehicles May 1.

Other park roads such as the Moose-Wilson Road, Signal Mountain Summit Road, Antelope Flats Road, East Boundary Road, Mormon Row Road, Two Ocean Road and Grassy Lake Road remain closed to vehicle traffic when posted or gated in the spring. These roads may close temporarily to accommodate snow removal operations. The opening dates of these roads vary from year to year and are dependent on weather, snow conditions, plowing progress, wildlife activity and road conditions.

The paved multi-pathways in the park are open to use when they are predominantly free of snow and ice.
